Raritan Borough sits along the Raritan River in Somerset County and is one of the area's most flood-prone communities. The borough's position at the confluence of the Raritan River and the North Branch of the Raritan creates significant flooding risk, and many of Raritan's older homes have aging foundations that have been repeatedly stressed by flood events over the decades.
Raritan's older residential neighborhoods feature a mix of Victorian-era and early 20th-century homes with stone and block foundations. The borough's flat terrain near the rivers means that floodwater can spread quickly across neighborhoods, and the high water table persists long after flood events recede.
Common Waterproofing & Foundation Challenges in Raritan, NJ:
- Position at the confluence of the Raritan River and its North Branch
- Frequent and significant flooding events that stress foundation walls
- Persistently high water table near the river corridors
